Title: P-code-aided global positioning system receiver
Inventor: KEEGAN RICHARD G
IPC: G01S1/00
Filed: 1990-09-21
Abstract: Method and apparatus for use in a global positioning system,(GPS), to obtain the benefit of L2 carrier signals and precise-code (P-code) signals transmitted from satellites in encrypted form. Received, encrypted P-code signals are correlated with a locally generated P-code sequence and the resulting signal is band-pass filtered and squared, to separate one satellite signal from the others, to recover the carrier signal and make accurate measurement of its phase and pseudo-range, even though the received P-code sequence is encrypted. Because the squaring step is performed over a narrower bandwidth than the original P-code, there is less degradation in the signal-to-noise ratio of the received signal, as compared with squaring over the entire P-code bandwidth. Therefore, performance is more reliable under weak signal conditions or when there are interference signals present, and the improvement in signal quality means that cycle ambiguity of the carrier signals can be resolved more rapidly. Moreover, the invention does not frustrate the intended purpose of P-code encryption.

Patent CA-2032284-A1 (CA)
Inventor: LEMKE JAMES U
IPC: G11B23/50
Filed: 1990-12-14
Abstract: An information storage apparatus is disclosed for reading and/or writing information on a rigid disk (10) which includes a non-Newtonian liquid bearing interface (70) between a transducer (21) and a storage medium (10), instead of a conventional air of Newtonian liquid bearing. The non-Newtonian liquid has a composition which exhibits plastic or pseudoplastic flow at high rates of shear. Preferably, the liquid is of the class of compounds whose viscosity shows a negative dependence on shear rate. Thus, as the relative speed of the transducer and the storage medium increases, while their relative spacing decreases, the increasing shear rate to which the liquid bearing is subjected causes the viscosity of the liquid to reduce. Resultantly, very low flying heights can be achieved, which increases the potential storage density on the storage medium, while the reduced drag exerted on the transducer by the lowered viscosity greatly reduces the power required to rotate the medium. <IMAGE>
